Question about Cars & Trucks
Was driving and the air conditioner quit blowing cold. Then the temperature gauge went to hot. Then the check engine light went on and the car would accelerate but didn't want to accelerate. Ideas? Thoughts?
Check for codes & diagnose the various issues

I would first check to see if both heater hoses are hot to the heater.
if 1 is hot and 1 is cold the heater control valve is closed or the heater core is plugged.

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

simply "adding a can"is a good way to end up with non-functional A/C. the typical system has high/low pressure switches that enable/disable the system. you need to be at the correct volume of refrigerant as specified on the sticker under the hood. i recommend using the proper equipment, evacuating, pulling a vacuum, and then refilling the system with the appropriate amount.
